PAPER BOX.

SPECIFICATION forming part of Letters Patent No. 471,400, dated March 22, 1892.

Application filed December 14, 1891 Serial No. 414,988. (No model.)

' and represent, in

Figure 1, the blank as prepared for folding into box shape; Fig. 2, a perspective view illustrating the method of folding the blank into box shape; Fig. 3,aperspective viewof the box complete; Fig. 4, a modification in the shapeof the tongues.

This invention relates to an improvement in that class of paper boxes such as are provided with a removable cover, and particularl y to that class which are made from blanks cut to the required shape and scored, and so as to be sold or shipped in fiat blanks to be set up by the user, and in which the blank contains within itself means forsecuring the folds together in the set-up position, the object of the invention beinga simple construction and which when set up will be secure; and theinvention consists in the construction as hereinafter described, and particularly recited in the claim.

The blank is representedin Fig. 1. It is in length corresponding to the length of one side and the height of both ends and of a width corresponding to the width of the complete box plus the height of the two sides. Broken lines on the drawings indicate scores to facilitate the bending or folding. The portion A within the scores represents the bottom of the box. The blank is as much wider than the width of the bottom of the box as required for the two sides B B. The scores a a, running and upon which the ends are turned up. Broken lines cZ-represent the scores between the ends C and theirrespective flaps D D. The distance between the scores 1) and d corresponds substantially to the height of the sides B B, and the, projection of the flap D is less than the depth of the box. At the end of each sideB is a projecting flap E. The scoresb run across between the two sides and the said flaps, as shown; but between the ends C and the two flaps a cut F is made at each side. The cut of the blank as thus far described does not differ materially from other known blanks for the formation of boxes. In each of the flaps E a tongue G is formed, projecting outward or from the ends 0, as shown. These tongues are best formed by cut-tin g a semicircular slit H, as shown, which leaves the tongue of corresponding shape, but so as to project outward. This completes the blank. In folding, the two sides B B are turned up from the bottom A, as seen in Fig. 2, and the flaps E E are turned inward at right angles to the sides and so that the tongues G then project upward toward the upper edge of the flaps. This done, the end C is turned upward outside the flaps E E and the flap D of the end turned over inward and its edge tucked inside the tongues G, as seen in Fig. 3. The width of the flap D and the position of the tongues are governed by each otherthat is to say, the tongues are out distant from the edge of the flaps E,in which they are formed, corresponding to the depth of the flap D. The flap D being tucked inside the flaps G, as described, the tongues serve to hold the flap D in that turned-in position, and thus secures the box in the set-up position, as the flaps E cannot be withdrawn without first withdrawing the flap D. Consequently the box is substantially as firmly secured in the set-up position as if the flap D were pasted to the flaps E, as in the usual construction.

Instead of making the tongues semicircular, as shown, the cuts may be made V shape, as seen in Fig. 4, the shape being immaterial, it only being essential that the cuts shall be so made as to produce upwardly-projecting tongues on the flaps E when the flaps are turned to place, and which tongues are adapted for the introduction of the flap D between them and the flaps in which the tongues are formed.

The illustration and description of the formation of the blank and folding as described for the box itself apply equally as well for the cover, and the illustration is the same. The two parts may be made identical except as to size, the cover being so much larger as to set down over the body of the box, as usual 1n making this class of boxes, or the cover may be of any other known construction; or this construction may be employed for the cover for a box of other construction. By the term box, therefore, as used in the claim, I wish to be understood as including the construction,whether it be used for a box or for a cover.

In United States Patent No.329,951, granted to me, a box is shown in which the two sides of the blank are constructed with proectmg flaps of a length corresponding to the width of the box and so that when the sides are turned up and the two flaps turned inward the said flaps extend across the end of the box, and one of the flaps is constructed with a tongue and the other with a slit, so that the tongue passed through the slit interlocks the two flaps across the end,

and then the end of the box is turned upward, with a flap at its outer edge turned over and inward to engage the tongue of one.

side flap, which projects through the slit in the other side flap, thus producing abox having its end of three thicknesses. The present invention, which is an improvement upon that patent, has the side flaps about half the length of the width of the box and they are not interlocked with each other, but are secured in place by a [lap on the end turned over and inward to engage a like tongue formed in each of the two side flaps, thereby in this application making the end of the box of but two thicknesses instead of three, as in the previous patent. I therefore do not wish to be understood as claiming anything shown in the said patent.

I am also aware that prior to my invention a blank for a box has been constructed with slits in the inwardly-turned portions which are adapted to engage the corners of a flap projecting from the sides or ends, as the case may be, and whereby the box is secured in the upright condition. I therefore do not broadly claim such engagement of the flaps.

I claim- A paper box consisting of a blank forming the bottom A, the sides B B, and the ends 0 0, all projecting from the bottom,each of the sides B B having a flap E projecting from its ends of substantially half the width of the box, the said flaps separated from the ends, each of the flaps constructed with a tongue G, projecting toward the outer or upper edge of said flaps, the ends 0, constructed with a flap D upon their outer edge, adapted to be turned over upon the inside of the flaps E and between the said tongues and the flaps in which the tongues are formed, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
